4. kill tester tcpdump
killall tcpdump
5. tester check packet number
tcpdump -vv -r /tmp/tcpdump_ens9f1.pcap 2>/dev/null | grep "seq" | grep "length"
Results:
========
length 10708
Expected Result:
================
length 128

net: add tunnel length in UDP tunnel parsing
Currently, the tunnel length info is not available when get the tunnel packet type with UDP port. This patch adds the parsing of the tunnel length info.
Additionally, adding comments for the inner_l2_len field and the tunnel_len field would help in understanding their.
